Three bank employees are using the corporate network. The first employee uses a web browser to view a company web page in order to read some announcements. The second employee accesses the corporate database to perform some financial transactions. The third employee participates in an important live audio conference with other corporate managers in branch offices. If QoS is implemented on this network, what will be the priorities from highest to lowest of the different data types? - Answer- Audio conference, financial transaction, webpage
Which firewall feature is used to ensure that packets coming into a network are legitimate responses to requests initiated from internal hosts? - Answer- Stateful Packet Inspection
What are three primary functions provided by layer 2 data encapsulation - Answer- Data link layer addressing
Detection of errors through CRC calculations
Delimiting groups of bits into frames

What is the network mask (subnet mask) for an IP address that has a CIDR prefix of /28 ? - Answer- 255.255.255.240
Which two protocols function at the internet layer? - Answer- IP
ICMP
A company has a network address of 192.168.1.64 with a subnet mask of 255.255.255.192. The company wants to create two subnetworks that would contain 10 hosts and 18 hosts respectively. Which two networks would achieve that? - Answer- 192.168.1.64/27 and 192.168.1.96/28
What is a key characteristic of the peer-to-peer networking model? - Answer- Resource sharing without a dedicated server
What is the network mask (subnet mask) for an IP address that has a CIDR prefix of /27 ? - Answer- 255.255.255.224
A user reports a lack of network connectivity. The technician takes control of the user
machine and attempts to ping other computers on the network and these pings fail. The technician pings the default gateway and that also fails. What can be determined for sure by the results of these tests? - Answer- Nothing can be determined for sure at this point
A network administrator is troubleshooting connectivity issues on a server. Using a tester, the administrator notices that the signals generated by the server NIC are distorted and not usable. In which layer of the OSI model is the error categorized? - Answer- Physical layer
Under which two circumstances will a switch flood a frame out of every port except the port that the frame was received on? - Answer- The frame has the broadcast address as the destination address
The destination address is unknown to the switch
What unique address is embedded in an Ethernet NIC and used for communication on an Ethernet network? - Answer- MAC address
If data is being sent over a wireless network, then connects to an Ethernet network, and eventually connects to a DSL connection, which header will be replaced each time the data travels through a network infrastructure device? - Answer- Data Link
What is the subnet mask for an IP address with a CIDR prefix of /16? - Answer- 255.255.0.0
Which two OSI model layers are considered to be included in the top layer of the TCP/IP protocol stack? - Answer- Session and presentation
At a minimum, which address is required on IPv6-enabled interfaces? - Answer- Link
local
What is the benefit of using cloud computing in networking? - Answer- Network capabilities are extended without requiring investment in new infrastructure, personnel or software
After making configuration changes on a Cisco switch, a network administrator issues a copy running-config startup-config command. What is the result of issuing this command? - Answer- The new configuration will be loaded if the switch is restarted
An IPv6 enabled device sends a data packet with the destination address of FF02::2.
What is the target of this packet? - Answer- All IPv6 configured routers on the local link
A wireless host needs to request a IP address. What protocol would be used to process the request - Answer- DHCP
An Internet television transmission is using UDP. What happens when part of the transmission is not delivered to the destination? - Answer- The transmission continues without the missing portion
Where are Cisco IOS debug output messages sent by default? - Answer- Console line
